flu shot

Darcy
I've never gotten the flu shot before in my life but now that I'm pregnant I'm considering it.  I'm only about 7 weeks and my work is offering free shots next week but I'm nervous about getting one since I've never had one before and with being so early in the pregnancy.  Should I get it now or wait till I'm a little further along? I'm not due till June so I will obviously be pregnant during all of flu season.  Like I said I've never had the shot before so I'm nervous about how I would react to it with it being my first shot and my first pregnancy...thoughts?
